Mg + Cl2 -> MgCl2 5.00 g Mg / 24 g/mol / 1 (from balanced equation) = 0.21 10.0 g Cl2 / 71 g/mol / 2 (from balanced equation) = 0.070 Smallest number is limiting reactant = Cl2 Yield = 10.0 g Cl2 / 71g/mol X 1 mol MgCl2/1 mol Cl2 X 95 g MgCl2/mol = 13.4 g

10 g Cl2 / 71 g/mol /1 (balanced equation) = 0.141 Still the limiting reactant\ MgCl2 is still 13.4 Sorry!
